Host cabling
This chapter provides examples of cabling topologies between one or more hosts and a controller
shelf or controller-drive tray. Direct-attach topologies, fabric topologies, and mixed topologies are
addressed.
You have several options for cabling between one or more hosts and a controller shelf or controller-
drive tray. Options include direct-attach topologies, fabric topologies, and mixed topologies. The
examples provided in this chapter show basic concepts to help you define an optimal host-cabling
topology. You are not limited to using only these topologies. A table that lists the maximum
supported number of hosts is included.
For host port locations on the specific controller shelf or controller-drive tray model that you are
installing, see
on page 22.
Note:
If you are using the Synchronous Mirroring feature or the Asynchronous Mirroring feature,
Hardware installation for Synchronous Mirroring and Asynchronous Mirroring
for information on cabling for these features.
Host interface connections
Each controller in an E5700 controller shelf (E5724 and E5760) or EF570 flash array have the
following options for built-in (base) ports:
•
Dual 10-Gb/s iSCSI connections (optical)
•
Dual 16-Gb/s Fibre Channel connections (optical)
Each controller in an E5700 might also have an optional HIC installed.
The E5600 controller-drive trays (E5612, E5624, and E5660) and the EF560 flash array connect to
hosts through one HIC on each controller.
Each controller in an E2800 controller shelf (E2812, E2824, or E2860) has one of the following
options for built-in (base) ports:
•
Dual RJ-45 ports for 1-Gb/s or 10-Gb/s iSCSI connection
•
Dual SFP ports that can be configured for 1-Gb/s or 10-Gb/s iSCSI connections or for 4-Gb/s, 8-
Gb/s or 16-Gb/s Fibre Channel connections
Each controller in an E2800 controller shelf might also have an optional HIC installed.
Each controller in an E2700 controller-drive tray (E2712, E2724, or E2760) has built-in (base) SAS
connectors for host connections and might also have an optional HIC installed
The following table shows host cabling configurations for the E5700 controller shelf and the EF570
flash array.
